Im wondering because i really want a sport bike but im only 5ft 6 nd my legs from flat foot to crotch are only about 28-29 inches nd ive been reading that sport bikes on average are about 31 inches tall, so shaving the seat would be the first thing i could do. How would i go about doing that? MOST importantly how much would that lower the seat height for me?? should i just give up on riding a sport bike?
